Description
Size: Length of carapace: 22 mm.
Breadth of carapace: 28 mm.
Breadth of front: 8mm.

Color: There seem to be two color variations:
(1) with greyish white carapace (when denuded), tending to a very faint blue.
(2) a whitish carapace blotched with bright brick-red, legs striped with the same colors.

This species can be distinguished by the upper margin of the orbit having two distinct notches, the outer orbital angle being sharp but not spinular, and the presence of a subhepatic spine just below it. The carapace, legs and chelipeds (with the exception of the fingers and thelower border of the hand) are concealed by a thick, dark, shaggy coat of hair.
